Oh, I see..... if that happens, I just hope it doesn't backfire & turn into a religious fiasco....

why?? well, it's already smack dab within the WTC. It was already pretty much a risky gambling with having a Mosque there so close to it. What I'm trying to say is, I completely understood your POV. I already thought from the beginning, it was already a bit of a gamble but I had confidence that they could face it just the way it is. But having a Mosque, Church, & Synagogue in the same building?? well, on one side it would build a bridge of reconcilliation between the three religions. On the other side, if they have some radicals (all 3 of them; Ulamas, Rabbis, Priests) that could turn ugly. Not to mention it would be so easy to take advantage of the controversial location. So, if they're planning on having those 3 places of worship there, they're gonna have to be extra careful. It would be easier to control one instead of three, you know.
But however, I would definitely support that suggestion. I really hope we can find a more common ground with other religions.
@Uzu: Umm....9/11 was the bane of our existence in the 21st century. I think this will help heal some wounds & not only that, help prevent younger Muslim generations from becoming terrorists.
